1243203-32-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243203-32-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,2,0 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1243203-32:
(9*1)+(8*2)+(7*4)+(6*3)+(5*2)+(4*0)+(3*3)+(2*3)+(1*2)=98
98 % 10 = 8
So 1243203-32-8 is a valid CAS Registry Number.

Material applications of novel disperse and mordent azo dyes based on 2-hydroxy-4-methoxybenzophenone
Dixit,Patel
experimental part, p. 921 - 928 (2012/03/26)
Novels disperse and mordent azo dyes were prepared by coupling of various diazo solutions of aromatic amines with 2-hydroxy-4-methoxybenzophenone. The resultant dyes were characterized by elemental analyses, IR and 1H NMR spectral studies. The
